She used to make 1 set of pictures per week when I was subbed. However these are very expensive, like 35-55 dollars and you need to add passes transaction fees, VAT etc. for just 10-15 pictures.
It is all lingerie/bikini pics, where some (like 3-4) have some clear butt shot. Apparently she did sell some video content but they were extremely short (10-15 seconds) for even higher prices. At this point doubt she will ever do anything more, even "soft nudity" like hand-bra shots etc. I think lingerie is as far as she will ever go.
It is certainly not a "good bargain" for most men of culture like us and this partially explains why leaks are very rare.
But the main problem is that Passes uses a plethora of DRM strategies that make it hard to download source quality files. Also said files are filled with watermaks and removing them is a chore.
If one leaks one of those pictures without removing the watermarks, Passes is able to trace back to the user who bought the pictures on their platform. Several of the leaks that came out in the previous months/years had watermarks, you can still see them in the main thread, the original leakers were certainly all perma-banned very swiftly by Passes so they will not be able to leak newer sets...
This in a nutshell is why we are not getting leaks.
